Description

本発明は、特にターボ機械のための、2つの中間伝達ラインを持つ減速機に関する。   The present invention relates to a speed reducer with two intermediate transmission lines, especially for turbomachines.

従来技術は、特に、文献米国特許第3772934号明細書、欧州特許出願公開第0636813号明細書、および国際公開第2013/150229号を含む。   The prior art includes, inter alia, the documents US Pat. No. 3,772,934, European Patent Application Publication No. 0636813, and International Publication No. 2013/150229.

ターボ機械は、1つまたは複数の機械的減速機を備えることができる。これは、特に、プロペラが減速機を使ってタービンシャフトによって回転させられるターボプロップエンジン機の場合である。   A turbomachine may comprise one or more mechanical reducers. This is especially the case for turboprop engine machines where the propeller is rotated by a turbine shaft using a speed reducer.

遊星歯車減速機構、チェーン歯車、ウォームギア、中間伝達ライン、等のような、多くの種類の減速機がある。本発明は、主として、伝達ラインを持つ減速機(複合減速機とも呼ばれる)に関する。   There are many types of reducers, such as planetary gear reduction mechanisms, chain gears, worm gears, intermediate transmission lines, and so on. The present invention mainly relates to a reduction gear having a transmission line (also called a compound reduction gear).

現在の技術においては、この種の減速機は、入力ラインと2つの中間伝達ラインを使って入力ラインによって駆動される出力ラインとを備える。入口ラインによって伝達される動力は、出力ラインに伝達される前に中間ラインの間で分割される。中間伝達ラインは、平行であり、一般に、入力ラインと噛み合う入力歯車および出力ラインと噛み合う出力歯車を担持するシャフトをそれぞれ備える。異なる歯車の歯数を変化させることによって、入力ラインと出力ラインとの間の減速比を得ることができる。この構造は、限られた空間において、および制御された質量によって大きな減速が可能である。   In current technology, this type of reducer comprises an input line and an output line driven by the input line using two intermediate transmission lines. The power transmitted by the inlet line is split between the intermediate lines before being transmitted to the output line. The intermediate transmission lines are parallel and generally each include a shaft carrying an input gear meshing with the input line and an output gear meshing with the output line. By changing the number of teeth of different gears, the reduction ratio between the input line and the output line can be obtained. This structure can be greatly decelerated in a limited space and with a controlled mass.

定義により、この種の減速機は、不静定システムである。特定の構成がなければ、一方の中間ラインはモータ動力の大部分にこれを通過させることができるが、他方の中間ラインは事実上いかなる動力の流れも起こらない。   By definition, this type of reducer is an indeterminate system. Without a specific configuration, one intermediate line can pass most of the motor power through, while the other intermediate line does not cause virtually any power flow.

したがって、動力の半分が減速機の中間ラインの各々を通過することを確実にするように、上述の種類の減速機の中間ラインの間に負荷を分配させる必要性が存在する。   Therefore, there is a need to distribute the load between the intermediate lines of the above-described types of reducers to ensure that half of the power passes through each of the intermediate lines of the reducer.

1つの解決策は、入力ラインの1つの端部を旋回結合するためのボールソケット手段と、入力ラインの反対側の端部の半径方向の動きを減衰させるための手段とを設けることから成る。   One solution consists of providing ball socket means for pivoting one end of the input line and means for dampening radial movement of the opposite end of the input line.

入力ラインは、(その長手方向軸線に対して)半径方向に動きやすい。これは、たとえば、モータシャフトに関して、入力ラインの端部の1つが旋回可能に取り付けられることによって可能になる。したがって、入力ラインの反対側の端部は、半径方向に動くことができ、これらの動きは減衰される。旋回および減衰のためのこれらの手段は、負荷を分配させるための手段を形成し、これは、次のように機能する。中間ラインの一方がより多く負荷される、すなわち、このラインを通過するトルクが他方のラインを通過するトルクより大きいならば、この場合、トルクによって生成される入力ラインの歯車の応力は、一方の側が他方よりも大きい。したがって、力が入力歯車に加えられることになり、これは、入力ラインの半径方向の動きをもたらすことになる。この動きにより、遊びが入力ラインのレベルで再平衡されるようになっている。平衡されると、中間ラインのトルクによって歯車に置かれる応力は相殺し、これは、中間ラインのトルクが等しいことを意味する。   The input line is easy to move in the radial direction (relative to its longitudinal axis). This is possible, for example, with respect to the motor shaft by one of the ends of the input line being pivotally mounted. Thus, the opposite end of the input line can move radially and these movements are attenuated. These means for swiveling and damping form a means for distributing the load, which functions as follows. If one of the intermediate lines is more heavily loaded, i.e. the torque passing through this line is greater than the torque passing through the other line, then the input line gear stress produced by the torque will be The side is larger than the other. Thus, a force will be applied to the input gear, which will result in radial movement of the input line. This movement causes play to be rebalanced at the input line level. When balanced, the stress placed on the gear by the midline torque cancels out, which means that the midline torque is equal.

しかしながら、この解決策は、歯車のミスアライメントを招く場合がある。この整列してない動作が原因で、ギア歯の「クラウニング」型の補正が必要とされる。この補正は、歯の面圧の増加を招く。加えて、ミスアライメントが大きな影響を与える場合は、たとえクラウニングを適用しても、必ずしも減速機の許容可能な動作を確実にすることができるとは限らない。   However, this solution may lead to gear misalignment. Due to this misaligned movement, a "crowning" type correction of the gear teeth is required. This correction leads to an increase in tooth surface pressure. In addition, if misalignment has a significant impact, even if crowning is applied, it is not always possible to ensure acceptable operation of the reducer.

本発明は、上述の問題に対する簡単で効率的で経済的な解決策を提案する。   The present invention proposes a simple, efficient and economical solution to the above problem.

本発明は、入力ラインと、中間ラインを使って入力ラインによって駆動される出力ラインとを備える、特にターボ機械用の2つの中間伝達ラインを持つ減速機にして、これらの中間ラインが実質的に平行である減速機であって、前記中間ラインの間に負荷を分配する手段を備え、この負荷分配の手段が、入力ラインの第1の端部を旋回結合するためのボールソケット手段と、入力ラインの前記第1の端部の半径方向の動きを減衰させるための第1の手段と、入力ラインの第2の反対側の端部の半径方向の動きを減衰させるための第2の手段と、を備えることを特徴とする、減速機に関する。   The present invention provides a reducer having two intermediate transmission lines, in particular for turbomachines, comprising an input line and an output line driven by the input line using the intermediate line. A reduction gear that is parallel and comprises means for distributing a load between said intermediate lines, said means for distributing load being ball socket means for pivotally coupling the first end of the input line; First means for attenuating radial movement of the first end of the line; and second means for attenuating radial movement of the second opposite end of the input line; The present invention relates to a speed reducer.

本発明の背後にある原理は、入力ラインを2つの離れている減衰手段に取り付けることである。本発明により、入力ラインがミスアライメントなしに垂直に動くことができるようになっている。   The principle behind the present invention is to attach the input line to two separate damping means. The present invention allows the input line to move vertically without misalignment.

前記第1および第2の減衰手段は、入力ラインの歯車の両側に取り付けられ、
前記第1および第2の減衰手段()は、前記歯車から等距離に位置しており、ローラは、各ローラ上で同じ動きをするように、したがって歯のミスアライメントを回避するようにギア歯から等距離に配置され得る。

図1は、2つの中間伝達ラインを持つ減速機10を非常に概略的に示しており、前記減速機1は、主として、4つの部分、すなわち入力ライン12と、出力ライン14と、入力ライン12によって駆動され、次には出力ライン14を駆動する2つの中間伝達ライン16とを備える。   FIG. 1 very schematically shows a speed reducer 10 with two intermediate transmission lines, said speed reducer 1 mainly comprising four parts: an input line 12, an output line 14, and an input line 12. And then two intermediate transmission lines 16 for driving the output line 14.

減速機の異なる部分12、14、16は、一般に、ここには示されていない減速機ケーシングに取り付けられ、この減速機は、たとえば入力ラインの通過、およびターボ機械の第1の構成要素へのその接続のための第1の開口部と、出力ラインの通過、およびターボ機械の第2の構成要素へのその接続のための第2の開口部とを備える。たとえば、第1の構成要素は、ターボ機械のタービンシャフトであり、第2の構成要素は、ターボ機械がターボプロップエンジン機である場合にはそのターボ機械のプロペラの駆動シャフトである。   The different parts 12, 14, 16 of the speed reducer are generally attached to a speed reducer casing, not shown here, which is for example passed through the input line and to the first component of the turbomachine. A first opening for the connection and a second opening for the connection of the output line and the connection to the second component of the turbomachine. For example, the first component is the turbine shaft of a turbomachine and the second component is the drive shaft of the turbomachine propeller if the turbomachine is a turboprop engine.

入力ライン12は、外歯を持つ歯車20を担持するシャフト18を含む。歯車20およびシャフト18は、同軸であり、Bとマークされた同じ軸線を中心として回転する。   The input line 12 includes a shaft 18 that carries a gear 20 having external teeth. Gear 20 and shaft 18 are coaxial and rotate about the same axis marked B.

出力ライン14は、外歯を持つ歯車24を担持するシャフト22を含む。歯車24およびシャフト22は、同軸であり、Aとマークされた同じ軸線を中心として回転する。この場合に、これらは、歯車20および入力ラインのシャフト18と同じ回転方向に回転する。   The output line 14 includes a shaft 22 that carries a gear 24 having external teeth. Gear 24 and shaft 22 are coaxial and rotate about the same axis marked A. In this case, they rotate in the same rotational direction as the gear 20 and the shaft 18 of the input line.

入力ライン12および出力ライン14は、平行である。したがって、それらの回転軸線A、Bは、平行である。   The input line 12 and the output line 14 are parallel. Therefore, their rotation axes A and B are parallel.

中間伝達ライン16は、実質的に平行であり、同一である。各ライン16は、第1の端部で入力歯車26を、および第2の端部で出力歯車28を担持するシャフト25を備える。出力歯車28は、出力ライン14の歯車24と噛み合う。入力歯車26は、入力ライン12の歯車20と噛み合う。歯車26、28は、外歯を有する。各シャフト25およびその歯車26、28は、同軸であり、軸線AおよびBに平行な、Cとマークされた同じ軸線を中心として回転する。   The intermediate transmission lines 16 are substantially parallel and identical. Each line 16 includes a shaft 25 that carries an input gear 26 at a first end and an output gear 28 at a second end. The output gear 28 meshes with the gear 24 of the output line 14. The input gear 26 meshes with the gear 20 of the input line 12. The gears 26 and 28 have external teeth. Each shaft 25 and its gears 26, 28 are coaxial and rotate about the same axis marked C, parallel to axes A and B.

先に説明されたように、この種の減速機10は、不静定システムであり、一方の中間ライン16はモータ動力の大部分にこれを通過させることができるが、他方の中間ラインは、事実上いかなる動力の流れも起こらない。図2でお分かりのように、動力または負荷のこの不十分な分配は、主として、歯車26は点Cで歯車20と接触しており、また中間ラインの一方の歯車28は点Dで歯車24接触しているが、歯車24と他方の中間ラインの歯車28との間のEで遊びがないことを確実にすることが困難であるという事実によるものである。   As explained earlier, this type of reducer 10 is an indeterminate system, with one intermediate line 16 allowing it to pass most of the motor power while the other intermediate line is Virtually no power flow occurs. As can be seen in FIG. 2, this inadequate distribution of power or load is primarily due to the fact that gear 26 is in contact with gear 20 at point C and one gear 28 in the intermediate line is gear 24 at point D. This is due to the fact that it is difficult to ensure that there is no play at E between the gear 24 and the gear 28 of the other intermediate line.

本発明は、減速機10に中間ライン16の間で負荷を分配するための手段を装備することによってこの問題に対する解決策を提案する。   The present invention proposes a solution to this problem by equipping the speed reducer 10 with means for distributing the load between the intermediate lines 16.

負荷の分配の一般的原理は、図3から図5に示されており、図6は、本発明の一実施形態を示している。   The general principle of load distribution is illustrated in FIGS. 3-5, and FIG. 6 illustrates one embodiment of the present invention.

入力ライン12のシャフト18は(その長手方向軸線に対して)半径方向に動きやすい。これは、たとえばタービンシャフトに関して、その端部の1つが旋回可能に取り付けられる(図5)ことによって可能になる。シャフト18の端部は、たとえば、減速機の入力ラインをタービンシャフトに接続するスリーブ32の相補的な溝に係合する旋回溝30を備える。半径方向の動きは、この時に、その旋回端部のレベルに位置している点の周りの入力ライン12の旋回として理解されるべきである。   The shaft 18 of the input line 12 is easy to move radially (relative to its longitudinal axis). This is possible, for example, with respect to the turbine shaft by one of its ends being pivotally mounted (FIG. 5). The end of the shaft 18 comprises, for example, a swivel groove 30 that engages a complementary groove in a sleeve 32 that connects the input line of the reducer to the turbine shaft. Radial movement is to be understood at this time as a swiveling of the input line 12 around a point located at the level of its swivel end.

したがって、入力ライン12のシャフト18の反対側の端部は、半径方向に動くことができ、これらの動きは、ばね34によって減衰される。   Thus, the opposite end of the shaft 18 of the input line 12 can move radially and these movements are damped by the spring 34.

中間ライン16の一方がより多く負荷される(図3)、すなわち、このラインを通過するトルクが他方のラインを通過するトルクより大きいならば、この場合、このトルクによって生成される入力ラインの歯車20の応力f1は、一方の側が他方よりも大きい。したがって、力Fが入力ラインの歯車20に加えられることになり、これは、入力ラインの動きをもたらすことになる。この動きにより、遊びが入力ラインのレベルで再平衡されるようになっている。平衡されると、中間ラインのトルクによって歯車20に置かれる応力f1、f2は相殺し、これは、中間ラインのトルクが等しいことを意味する。   If one of the intermediate lines 16 is loaded more (FIG. 3), ie the torque passing through this line is greater than the torque passing through the other line, in this case the input line gear produced by this torque The stress f1 of 20 is greater on one side than on the other. Thus, a force F will be applied to the input line gear 20, which will result in movement of the input line. This movement causes play to be rebalanced at the input line level. Once balanced, the stresses f1, f2 placed on the gear 20 by the intermediate line torque cancel, which means that the intermediate line torque is equal.

有利なことに、ばね34の減衰手段は、入力ライン12のシャフト18を案内するころ軸受36と組み合わされる。   Advantageously, the damping means of the spring 34 is combined with a roller bearing 36 that guides the shaft 18 of the input line 12.

上述のように、歯車のミスアライメントが、図5に示されるように発生する場合がある。この整列してない動作が原因で、ギア歯の「クラウニング」型の縦方向の補正が必要とされる。この補正は、歯の面圧の増加を招く。加えて、ミスアライメントが大きな影響を与える場合は、たとえクラウニングを適用しても、必ずしも減速機の許容可能な動作を確実にすることができるとは限らない。   As described above, gear misalignment may occur as shown in FIG. Due to this misaligned movement, a gear crown “crowning” type longitudinal correction is required. This correction leads to an increase in tooth surface pressure. In addition, if misalignment has a significant impact, even if crowning is applied, it is not always possible to ensure acceptable operation of the reducer.

本発明により、この問題が全体的な入力ライン減衰によって改善されるようになっている。   The present invention improves this problem by overall input line attenuation.

図6は、本発明の一実施形態の一実施例を示しており、その場合、上述の要素は同じ参照数字で示されている。   FIG. 6 shows an example of an embodiment of the present invention, in which the elements described above are indicated with the same reference numerals.

たとえばボール型の2つのころ軸受36が、入力ライン12の端部において歯車20の両側に取り付けられる。   For example, two ball-shaped roller bearings 36 are attached to both sides of the gear 20 at the end of the input line 12.

古典的には、各軸受36は、それぞれ内側および外側の2つのリングを備えることができ、その間にリング状の保持器によって保持され得る玉軸受の列が延在する。旋回溝30を備えるその端部と反対側に、第1の軸受36の内輪が入力ライン12のシャフト18の端部に固定して取り付けられる。第2の軸受36の内輪は、旋回溝30を備えるシャフト18の端部に固定して取り付けられる。   Classically, each bearing 36 can comprise two inner and outer rings, respectively, between which extend a row of ball bearings that can be held by a ring-shaped retainer. The inner ring of the first bearing 36 is fixedly attached to the end of the shaft 18 of the input line 12 on the side opposite to the end provided with the turning groove 30. The inner ring of the second bearing 36 is fixedly attached to the end of the shaft 18 having the turning groove 30.

減衰ばね34は、軸受36を支持する。第1のばね34は、第1の軸受36を支持し、第2のばね34は、第2の軸受36を支持する。好ましくは、ばね34は、同一である。好ましくは、ばねは、戻しばねである。有利なことに、それらは、歯車20から等距離に位置している。   The damping spring 34 supports the bearing 36. The first spring 34 supports the first bearing 36, and the second spring 34 supports the second bearing 36. Preferably, the springs 34 are the same. Preferably, the spring is a return spring. Advantageously, they are located equidistant from the gear 20.

旋回溝30を備えるシャフト18の端部は、減速機の入力ラインをタービンシャフトに接続するスリーブ32の相補的な溝に係合される。   The end of the shaft 18 with the swivel groove 30 is engaged in a complementary groove in the sleeve 32 that connects the reducer input line to the turbine shaft.

本発明は、図3および図4に関して先に述べたように機能する。図6に見られるように、中間ライン16の一方がより多く負荷される(図3)、すなわち、そのラインを通過するトルクが他方のラインを通過するトルクより大きいならば、この場合、このトルクによって生成される入力ラインの歯車20の応力f1は、他方の側よりも大きい。したがって、力Fが入力ラインの歯車20に加えられることになり、これは入力ラインの動きをもたらすことになるが、本発明のおかげで、これは位置ずれが生じることになることを意味しない。   The present invention functions as described above with respect to FIGS. As seen in FIG. 6, if one of the intermediate lines 16 is more heavily loaded (FIG. 3), ie if the torque passing through that line is greater than the torque passing through the other line, then this torque The stress f1 of the gear 20 of the input line generated by is greater than the other side. Thus, a force F will be applied to the input line gear 20, which will result in movement of the input line, but thanks to the present invention, this does not mean that a displacement will occur.
